SINGLE-TRAIL GUN-CARRIAGE.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed March 31, 1919. Serial No. 286,483.

To all 'whom it may concern:

Be it known that I, EUGENE SCHNEIDER, citizen of the French Republic,and a resident of 42 Rue dAnjou, Paris, France, have invented new anduseful Improvements in Single-Trail Gun-Carriages, which invention isfully set forth in the following specification.

This invention has for its object to provide an improved apparatus forallowing of obliquities of level between the front and rear portions ofsingle-trail gun carriages during firing, wherein the front portion isconstituted by an endless track, and wherein the gun is trained byshifting the trail.

According to this invention the trail is pivoted at its tail by means ofa pivot pin situated in its longitudinal axial plane,- to a slidingcarriage engaging an arc-shaped guide formed on an anchoring platformand adapted to turn on a center constituted by the axis of pivotation ofthe gun pedestal upon the endless track. By this means the wholecomposed of the anchoring platform and the sliding carriage are able tohave, during firing, inequalities of level relatively to the wholecomposed of the trail and the front support of the gun constituted bythe endless tracks.

Two forms of construction and application of this invention areillustrated by way of example in the accompanying drawings in which:

Figures 1 to 4: illustrate a first constructional form.

Fig. 1 is a side elevation partly in vertical section of the guncarriage in the firing position.

Fig. 2 is a plan partly in section on the V line IIII of Fig. 1.

Fig. 3 is a cross section on the line III-III of Fig. 1.

Fig. 4 is a cross section on the line IVIV of Fig. 1.

Figs. 5 to 7 illustrate a second constructional example of theinvention;

Fig. 5 is a side elevation partly in section showing the gun carriage infiring position;

Fig. 6 is a horizontal section on the line VIVI of Fig. 5;

Fig. 7 is a cross section on the line VIIVII of Fig. 5.

As shown in Figs. 1 to 4, the gun carriage trail A is trunnioned in theusual manner on a gun pedestal B which is adapted in its turn to rotatein or on a frame C resting on the endless track trucks D.

According to this invention, the trail A is jointed by means of its tailA along its longitudinal axis aa to a sliding carriage E engaged-on anarc-shaped guiding track f formed on an anchoring platform F of knownconstruction. The joint between the tailA and the carriageE may beefiected as shown, by means of a pin a formed on the tail and engaged ina corresponding bearing in the sliding carriage E. The retention of thetail in the sliding carriage is assured by guide ribs a engaging grooves6 formed in the sliding carriage. The joint may however be effected inthe reverse manner by providing a pin on the carriage E working in acorresponding bearing formed in the tail A The shifting of the guncarriage for the purpose of training the gun may be produced by means ofany known mechanism acting upon the carriage E. In the example shown inFigs. 1 to 1, a nut G is mounted on a screw H which is journaled at itsends in bearings h on the platform F. The nut G is held between twocheeks E of the carriage E. By actuating the screw H by means of aratchet key I, the nut G and the carriage E can be moved in the desireddirection.

It will be readily understood that in firing, the platform F will beable to have obliquities of level relatively to the front supports ofthe gun carriage without any, injurious effect being produced upon theanchoring of the gun carriage.

In the example shown in Figs. 5 to 7, the frame C on which the gunpedestal B is pivoted, is movable about a transverse axle K journaled atits ends in bearings L formed on or carried by the two endless tracktrucks D. This manner of connection between the gun carriage and theendless track trucks forms the subject matter of another application forpatent by the present applicant, filed February 28, 1919, Serial No.279,879.

The frame C is. fixed by means of two arms G to one of the endless tracktrucks D. The manner in which the present invention is carried intoeffect is practically the same in this example as in the precedingexample. By way of modification, the

mechanism for shifting the carriage E along the arc-shaped guide trackF, is different from the one shown in Figs. 1 and 2.

The arc-shaped track Fis formed with teeth F with which engages a pinion1W fixed on a spindle m journaled in the carriage E. This spindle isadapted to receive at its outer end a ratchet key N.

In both the examples hereinbefore described, when the gun carriage is inposition for firing, the anchoring platform F may be connected to one ofthe endless track trucks D by means of rods P provided with turnbucklesfor adjusting their length.

lVhat I claim is 1. The combination with a trail gun-carriage, amounting on which is pivoted the trail at its forward end to havehorizontal angular movement around its pivotal point, an anchoringplatform having an arcuate guide centering with the pivotal point of thetrail, and a carriage having a pivotal connection with the trail-tail inalinement with the longitudinal axis of the trail, said carriage beingslidable on the arcuate guide of the anchoring platform to shift thetrail around its forward pivotal point.

2. The combination with a trail gun-carriage, a mounting on which ispivoted the trail at its forward end to have horizontal angular movementaround its pivotal point, an anchoring platform having an arcuate guidecentering. with the pivotal point ofthe trail, a carriage having apivotal connection with the trail-tail in alinement with thelongitudinal axis of the trail, said carriage being slidable on thearcuate guide of the anchoring platform to shift the trail around itsforward pivotal point, and means on the anchoring platform for movingthe slidable carriage on the arcuate guide. 7

3. The combination with a trail gun-carriage, a mounting on which ispivoted the trail at its forward end to have horizontal angular movementaround its pivotal point, an anchoring, platform having an arcuate guidecentering with the pivotal point of the trail, a carriage having apivotal connection with the trail-tail in alinement with thelongitudinal axis of the trail, said carriage being slidable on thearcuate guide of the anchoring platform to shift the trail around itsforward pivotal point, a screw rotatably mounted on the anchoringplatform, a nut held in the slidable carriage engaging the screw, andmeansfor rotating the screw to propel the nut to move the slidablecarriage on the arcuate guide.

4. The combination with a trail gun-carriage, a mounting on which ispivoted the trail at its forward end to have horizontal angular movementaround its pivotal point, an anchoring platform having an arcuate guidecentering with the pivotal point of the trail, a carriage slidable onthe arcuate guide of the anchoring platform, and a pivotal connectionbetween the tail-trail and the slidable carriage to permit relativeaxial movement between the trail and carriage to accommodate relativeobliquities of levels of the anchoring platform and of the front supportof the trail.

5. The combination with a trail gun-carriage, a mounting on which ispivoted the trail at its forward end to have horizontal angular movementaround its pivotal point, an anchoring platform having an arcuate guidecentering with the pivotal point of the trail, a carriage slidable onthe arcuate guide of the anchoring platform, an axial pin and bearingforming a pivotal connection between the tail-trail and the slidablecarriage to permit relative axial movement between the trail andthecarriage to accommodate relative obliquities of the levels of theanchoring, platform and the front support of the trail, and an engagedflange and rim connection between the trail-tail and the slidablecarriage to hold said members together.

In testimony whereof I have signed this specification.

EUGENE SCHNEIDER.
